Origin
Not yet written for this entry.
Description
Bai zhuo (白灼, literally white scalding) is the Cantonese technique of briefly poaching food — typically vegetables and seafood — in a light aromatic broth or salted water, then finishing with a drizzle of hot soy sauce and sizzling oil. The technique exemplifies Cantonese cooking philosophy: ingredients of impeccable freshness, handled minimally, dressed simply so that the ingredient's natural flavour is the point. Bai zhuo Chinese greens — morning glory, choy sum, or gai lan in a pool of oyster sauce and hot oil — is one of the most frequently ordered dishes in any Cantonese restaurant.

Flavour Context
Bai zhuo is one of the purest expressions of Cantonese freshness doctrine. It transforms greens into something simultaneously simple and profound — the clean sweetness of the vegetable against the umami of oyster sauce and the fragrance of the hot oil sizzle.
